Abstract
The utility model discloses a sealed dustproof oil cylinder for a forklift truck. The oil cylinder comprises a cylinder body and a piston, wherein piston rods are arranged at the two ends of the cylinder body; cylindrical plugs are arranged in cylinder ports in the two ends of the cylinder body; O-shaped sealing rings and Y-shaped dustproof rings are arranged on the inner sides of the cylindrical plugs; annular grooves are formed in the inner sides of the cylindrical plugs; the O-shaped sealing rings and the Y-shaped dustproof rings are clamped in the annular grooves. The oil cylinder is reasonable in design and convenient to use; annular grooves are formed outside the cylindrical plugs, and J-shaped sealing rings are arranged in the annular grooves outside the cylindrical plugs, so that a product has better sealing and dustproof effects, better using effects are achieved, the service life of the product is prolonged, energy resources are saved, and the efficiency of the product is improved.
Description
Technical field:
The utility model relates to a kind of fork truck oil cylinder, is specifically related to a kind of sealing and dustproof fork truck oil cylinder.
